Efficient top-k algorithm for eXtensible Markup Language keyword search

The ability to compute top-k matches to eXtensible Markup Language (XML) queries is gaining importance owing to the increasing of large XML repositories. Current work on top-k match to XML queries mainly focuses on employing XPath, XQuery or NEXI as the query language, whereas little work has concerned on top-k match to XML keyword search. In this study, the authors propose a novel two-layer-ba...

Keyword Search in Text Cube: Finding Top-k Relevant Cells

We study the problem of keyword search in a data cube with text-rich dimension(s) (so-called text cube). The text cube is built on a multidimensional text database, where each row is associated with some text data (e.g., a document) and other structural dimensions (attributes). A cell in the text cube aggregates a set of documents with matching attribute values in a subset of dimensions. A cell...

Scalable Continual Top-k Keyword Search in Relational Databases

Keyword search in relational databases has been widely studied in recent years because it does not require users neither to master a certain structured query language nor to know the complex underlying database schemas. Most of existing methods focus on answering snapshot keyword queries in static databases. In practice, however, databases are updated frequently, and users may have long-term in...

Top-K Correlation Sub-graph Search in Graph Databases

Recently, due to its wide applications, (similar) subgraph search has attracted a lot of attentions from database and data mining community, such as [13, 18, 19, 5]. In [8], Ke et al. first proposed correlation sub-graph search problem (CGSearch for short) to capture the underlying dependency between subgraphs in a graph database, that is CGS algorithm. However, CGS algorithm requires the speci...
